2x+1=7 I forgot how to do linear equations

x = 3

Step-by-step explanation:

In equations, your aim is to make x the subject so then you can solve it but you also have to keep in mind that both sides have to be equal so for example, if you decided to minus 1 from 2x you would have to do that to 7 as well to keep the whole equation equal because if you only minus 1 from 2x then you get a whole new equation so,

→ 2x + 1 = 7

⇒ We want isolate 2x so we subtract 1 from both sides as a first step

→ 2x = 6

⇒ The second step would be to divide both sides by 2 to isolate x

→ x = 3

the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.

if you could provide answer choices that might allow me to answer the question easier if my above answer isn't an option! (:

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
